Research of the photoelectric on-line sensor for detecting the residual capacity in a lead acid storage battery

摘要

Aimed at the puzzle of detecting the residual capacity in a lead-acid storage battery, this research tried to establish some relations between the energy of the reflecting light and the density of acid liquor in the battery. It was found that there is a one-to-one functional relationship between the density of acid liquor and the residual capacity in a lead-acid storage battery. This therefore suggests a kind of novel detecting method for the residual capacity in a lead-acid storage battery by using a photoelectric sensor. On this basis, the physical implementation of a photoelectric sensor for detecting the residual capacity in a lead-acid storage battery was studied. Finally, by experimental studies, discussed the influence on the relationship between the residual capacity in a battery and the change of the density due to temperature change was established. This permitted the design of an experimental device and procedures for detecting the residual capacity in a storage battery. The experimental results showed that this method is feasible in detecting the residual capacity in storage battery.
